THOMAS J. BUSH, OF LEXINGTON, KENTUCKY.

ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 709,961, datedSeptember 30, 1902.

Application` filed March 24, 1902.

To @ZZ whom, it muy concern:

Be it known that I, THOMAS J. BUSH, a citizen of the United States, residing at Lexington, Fayette coun ty,Kentucky,have Vinvented certain new and useful Improvements in Rotary Engines, of which the following is a specilication.

My invention relates to rotaryengines of the class in which steam or compressed air acts on the moving part.

The objects of the invention are to provide a simple and inexpensive rotary engine of few parts and in which the moving parts are all exposed to view for removal, cleaning, oiling, dac.; also to provide a rotary engine inwhich the actuating fluid is delivered from a rotary member against a loose horizontally-disposed lever-forming ring or band eccentrically dis posed within a fixed circular fulcrum ring or band and acting upon a transmitting .arm or lever carried by said rotary member to cause the same to be rotated and act as the driving pulley or means of the engine. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective of my improved rotary engine, parts being broken away. Fig. 2 is a plan thereof with parts in section. Fig. 3 is a central vertical section thereof on line 3 3, Fig. 2. Fig. 4: is a detail view showing a modified form of lever-ring.

A designates the base of the engine or motor frame, which may be secured to the floor or any suitable support, and from this base rise the standards A', supporting at their upper ends the centrally-apertured horizontal supporting-plate A2, provided with a circular iiange or fulcrum-ring A3. The base Ais further provided with a central verticallyadjustable externally-threaded socket 0 in which is stepped the lower end of the rotary vertical steam or air pipe B, the upper end of which extends up through the center of the plate A2, s'aid pipe being provided below said plate with aninlet b.

C is the steam or air cylinder or chamber, bolted or otherwise secured upon the under side of plate A2 and receiving the actuating fluid through a pipe e. This cylinder or chamber C is provided with any suitable form of packing-gland o where the pipe B passes Serial No. 99,700. (No model.)

through it, and the opening b in the pipe opens into this cylinder.

C' designates a discharge-pipe projecting from the pipe B and having an oblique port 0X in its outer beveled end to discharge the operbe termed a lever forming ring or band D, supported 'loosely uponthe horizontal plate A2. The port 0X extends in a direction contrary to the direction of rotation ot' the pipe C, so as to prevent any reactive moment from being established by the back pressure of' the operating fluid. By this arrangement of the port 0X I get a reactionary effect upon the end of pipe C as well as an impact upon the lever-ring. Y The power from the lever-forming ring D is transmitted to the rotary pipe or transmitting member B to rotate the same by means of a radial arm C2, which is provided at its outer end with an antifriction roller or wheel c5, which engages the inner wall of the said lever-forming ring D, this lever-arm C2 being in squared telescopic sections c2 c3 to prevent rotary movement one within the other, and the outer section is held in its adjusted positions by means of a screw c4. The radial arm C2 is provided with a collar c6, vhaving a screw c7, by means of which the arm may be held in its proper position onl the rotary member or pipe B. The forward side of the discharge end of this pipe C lies very close to the lever-ring D and, together with thelever-arm C2, always keeps a part of said ring D between said pipes and lever-arm against the fulcrum-ring A3, so that as the issuing fluid pressesagainst the ring D and the latter is forced outwardly at the point where the iiuid impacts the ring D will apply the same force to the outer end of the arm C2 in a direction centripetal to the ring D and causesaid arm to rotate the cylinder or head C. Thus the lever-forming ringD is continuously and slowly rolled on its periphery about the fulcrum-flange A3 in the direction of the arrow as, while the rotary pipe or member B is rotated in the direction of the arrow w', and while the lever-ring is thus being gradually rolled in the direction of the arrow 0c it will be slid outwardly on the supporting-plate A2 as the impact-point of the iiuid changes by the rotary movement of the ating fluid against the inner wall of what may l pipe B. It Willbe noticed that the lever-forming ring D is provided with upper and lower fianges d d and is corrugated between these flanges, as shown at d2, to receive the impact of the issuing duid. The antifriction-wheel engages the plain portion d2 of the ring above the flange d. The vertical adjustment of the pipe B is effected by means of its step-bearing a, and the similar adjustment of arm C2 is effected by its collar and screw c6 c7. In 11`ig.4 the ring D has aplaininnerwall. The power from the pipe B is transmitted from its pulley B3 by means ot a suitable belt E, or any form of gearing may be employed.

The discharge-pipe Cl is in telescopic seetions c2 c3, squared to prevent rotating one within the other, and the outer section is held in its adjusted position by a setscrew c4. The pipe C and arm C2 are preferably adjusted at an angle of about forty-tive degrees to one another.

It will be seen that the lever-forming ring D and the rotary member C and its connected parts may be readily oiled or removed when necessary and that worn or broken rings D may be readily replaced by others, and, moreover, all of the parts are exposed to view, and no slide or rotary valve mechanisms are neeessary.

The cylinder C is provided with a cock C4 for drawing ott the Water of condensation, and a pipe a5 leads from the plate A2 for the same purpose. A hood A5, having an exhaust-opening a5 in its top, may also be provided, as shown in dotted lines, Fig. 3.
